OVEREDGE SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 736,199, dated August11, 1903. Application filed July 25. 1902. SerialNo.116.980. (N0 model.)

To all whom it may concern.-

citizen of the United States Of America, residing in Providence, in thecounty of Providence and State of Rhode Island, have inventedImprovements in Sewing-Machines, of which the following is aspecification.

The object of my invention is to construct a sewing-machine for makingautomatically and with speed and economy an edging On lace, haircloth,or other open-work goods,

7 Be it known that I, STOCKTON BORTON, a

- such as to wholly prevent the appearance of whiskers on the finishededge of the goods and at the same time insure the secure attachment ofthe edging to the goods.

, In carrying out my present invention I use overseam orother overedgestitchingandpreferably employ cords to produce an edging embodying theinvention formingthe subject of my Letters Patent No. 556,300, datedMarch 10, 1896, and in making edgingpf the patented construction Iemploy the combination of mechanism forming the subject of my LettersPatent No. 561,043, dated May 26,1896. Although I prefer to employ cordsin making edgings on the machine of my present inven- 7 tion, I do notwish to .limit myself thereto.

By the term whiskers I'intend to designate the ends of the threads ofthe lace, haircloth, or other open-work goods which project beyond thecut edge of the goods and which have heretofore been liable to protrudebetween and beyond the overseaming-stitches "1. and the cords laidthereon. According to my present invention I provide means for brush-,ing back and laying on each other (and, if desired, bending or foldingunder or over the edge of the goods) these out ends of the threads orwhiskers as the goods are fed through the machine. This brushing devicemay be a simple edge-guide which is placed-between the needle and thetrimmer, as I will describe.

In the accompanying drawings, Figure 1 is aplanview of one form ofoverseam sewing;

machine in which my invention may be employed. Figs. 2, 3, and 4 aredetached views in plan, edge, and inverted plan of a form ofpresscr-foot which may be employed in carrying out my invention.

, Fig. 5 is a sectional view of a part of the machine, drawn to anenlarged scale, on the line 5 5, Fig. 6. Fig. 6' is a view looking inthe direction of the arrow, Fig. 5. Fig. 7 is a view, on a still largerscale, of parts to illustrate my invention; and Fig. 8 is a view of apiece of hail-cloth or like open fabric in process of being edged.

I do not wish to restrict myself to the use of any particularconstruction of overedge sewing and trimming mechanism for the purposeof carrying out my invention; but I prefer to employ the overseaming andtrimming machine for which patents were granted to myself and'OharlesII. Willcox April 5, 1892, Nos. 472,094 and 472,095. So much of themachine of said patents as is necessary to an understanding of mypresentinvention is illustrated in the drawings. Thus A represents thebed-plate, e the needle-bar carrying the needle 10, and h is the looper.The presserfoot q is carried by a resser-bar 35, which is attached to orinone piece with a sleeve 36, secured to the shaft 'r, Fig. l.- Parallelwith this shaft 1' is a shaft 8, carrying the vibrating arm 41, in theouter end of which is mounted the upper shear-blade 42 of the trimmingdevice, the lower blade 90 being adj ustably fixed in the frame, Figs. 5and 6.

The presser-foot q has in addition to the usual chaining-finger q adownwardly-projecting piece G underneath. A somewhat similar piece wasemployed in themachine of my Patent No. 561,043 as an eye for the lowercord to be fed to the underside of the edging, and I may employ thispiece in part for a similar purpose here if I use such under cord in theedging; but I provide this piece G in the present instance for anotherpurpose-namely, to serve as an edge-guide to bend or brush back theprojecting ends of the whiskers or ends of the threads cut by thetrimming device and before the goods reach the overedging devices inbeing fed through the machine. The cord-guiding notch in the piece G isbest illustrated in the side view of the Presser-foot, Fig. 3, but theedge-guiding part of the piece G is best illustrated in the enlargedview, Fig. 7.' The goods being fed. by the feed-dog m, Figs. 1 and 5,through the machine in the direction of the arrows Fi s.

7 and 8, the edge will first .be trimmed by the shearing action oftheblades 42 and 90, Fig.

' 7, and then the pr'ojecting cut ends or whiskers will be brushed backonto each other in the direction of the line of feed, and while in thiscondition the overedge-stitchforming devices will apply theoveredgestitches around these brushed-back whiskers,

no and so not only prevent their protruding through and between theoveredge-stitches, but also more securely hold the overedgestitchinginplace on the edge of the goods whether cords such as was be used or not.

:5 It will be seen that the important feature is thatnot only shall theedgeguide G be located between the trimmer and the stitchformingmechanism in the direction of the feed, Fig. 6, but that the edge-guideG shall lie between the trimming-line and the sewingline, Figs, 5, v7,and 8.. In order to insure that this edge-guide'G shall always lie inacertain relation to the needle 10 and between the latter and the trimmerin the direction at -right angles to the feed, vI make the presserarm36, which carries this guide, non-adjustable by aflixing to the shaft7', Fig. 1,.a collar 0, which bears against the housing 37 and'keepsthe-shaft r and the parts carried by it always as far to the leftaspossible. By this means the adjusting thumb-screw 40 has its flange420 bearing only against the trimmer only.

end of the shaft 5 to laterally. adjust the goods, whereby theoverseamingmay be formed over and inclose these bent ends, substantiallyasdescribed.

2. The combination of overedge sewing mechanism and trimmer mechanismwith .50 means between the trimmer and needle for bending back. inthedirection of the line of feed the cut ends of the threads of open-workgoods, and means for laying a cord over said cut'and bent ends, wherebythe overseaming maybe formedover and inclose the cord and bent ends,substantially as described.

' .In testimony whereof I have signed my name'to this specification inthe presence of two subscribing witnesses.
